Render html table with underscore template engine using a backbone complex model

Question

I\'m trying to render an html table using underscore template engine. First I have the JSON response from the server like this

{
    CurrentModel: {
                 


        

Answer 1

First, I would parse the data into the collection to get a list of the pages and maybe grab the CurrentModel definition :

var PageCollection = Backbone.Collection.extend({
    url: '/pages',
    model: Page,

    parse: function(response) {
        this.CurrentModel=new Page(response.CurrentModel);
        return response.Children;
    }
});

Then, with the row template set up as

<script id="tpl-page-list-item" type="text/template">
    <tr>
        <td><%= Metadata.Name %></td>
        <td><%= Metadata.Slug %></td>
        <td><%= Metadata.IsPublished %></td>
        <td><%= Metadata.Changed %></td>
        <td><input type='checkbox' /></td>
    </tr>
</script>

you can define your views more or less like you had them

var PageListItemView = Backbone.View.extend({
    template: _.template($('#tpl-page-list-item').html()),
    events: {
        "click input[type=checkbox]": "publish"
    },
    render: function (eventName) {
       var html=this.template(this.model.toJSON());
       this.setElement($(html));
       return this;
    },
    publish: function () {
        console.log(this.model.get("Metadata").Name);
    }
});

var PageListView = Backbone.View.extend({
    tagName: 'table',
    initialize: function () {
        this.collection.bind("reset", this.render, this);
    },
    render: function (eventName) {
        this.$el.empty();

        this.collection.each(function(page) {
            var pageview=new PageListItemView({ model: page });
            var $tr=pageview.render().$el;           
            this.$el.append($tr);
        },this);

        return this;
    }
});

Initialize the collection and the views, fetch the data, and you should have something equivalent to this Fiddle : http://jsfiddle.net/NtmB4/

var coll=new PageCollection();
var view=new PageListView({collection:coll})
$("body").append(view.render().el);

coll.fetch();
